                                For thousands of years, certain cyanobacteria have been part of the human diet, with documented consumption dating back to the Aztec civilization. These ancient, photosynthetic microorganisms, often called blue-green algae, are now recognized as nutrient-dense superfoods, with specific species being safely cultivated for human consumption.
